Work is a form of energy.Work done= force × displacement.
Force at an Angle
Work Done by a Force at an Angle is given by: 
Δ E = F Δ s
Work is done on an object when a force acting on it makes it move.Energy is transferred to the object as kinetic energy.Force at an Angle
Work Done by a Force at an Angle is given by: Work Done = F s cos θ
where F cos θ is the component of the force in direction of the displacement.
